The fix posted by several of you and beautifully illustrated by macvette has been proven once again. After years of frustration and now, an urgent need to solve the problem due to my spouse's health problem that prevents her from hopping up to adjust things manually, I stumbled upon this thread. Voila. Like magic. It was a good excuse to buy a new up-to-date battery-powered pencil soldering iron that is perfect for this kind of touch-up. Splendid. Now to see if I can do the same magic with the DVD player!

Interesting thread. I have a Kenwood VR-507 that actually still continues to work well to this day. The RC-R0720 remote on the other hand is unusable.Technically it works fine - but the plastic front, back, between the buttons - everywhere has become very sticky/tacky and it not very appealing to use.the remote has been either in a drawer, box, or sitting out for years but not used (universal remote controlling the AV and others instead of the R0720).

But now the other universal remote is gone and I wanted to use this.Any idea if it can be cleaned? I have tried spot cleaning different parts of it with various solutions to no avail.

I have older Kenwood remotes, RC-P7730 and RC-6040 are ion front of me currently.... any idea how well if at all they could control the VR-507?

I just wanted to say thanks to whoever help me out..Just like everyone else I bought a Kenwood VR-405 on ebay cheap,had no remote,but i have another kenwood that doesnt work but had the remote a RC-R0709,and i tried it and it worked for about 15 minutes,then stopped.i contacted kenwood they told me needed the correct remote rc-r0509.so i found one on ebay,today was hard to find,anyway put batteries in it same damm thing about 15 minutes and stopped,of course went to kenwood site owners manual online support says something about a four-digit code for remote or reset microprocessor,did that nothing...so..about to throw it acroos the room and punch the reciever i decided to google search for the 4 digit code stumbled here..seen where someone said to tap the bezel faceplate on front of the reciever,remote will work,i thought to myself,"ya right" so..for sh@ts and grins,i tried it took 3 taps each one alittle harder, and "by god.." it worked..so..i put batteries into the other remote the rc-ro709 and it works 2..what are the odds...you guys are f@@kin the best man..seriously,glad i didnt smash them..now i gonna try to find the pictures of the soldier pins to fix..once more people thanks alot man....

I’ll never buy a Kenwood (VR-407) again! Next problem I’ve had was my optical cable connection is now down to one! I purchased a switcher mono price so I still can use the receiver for surround sound for my 3 connections. What a piece of junk.

This looks as good a place as any to try. I have a VR-309 which has been good to me for many years. I moved and had not used it in a while (about 1yr). I always take the batteries out of the remote when I am not using it to prevent corrosion by way of leaky batteries... but it looks like this was a big mistake...

I know the IR receiver in the unit works because I can use an "all in one" remote to do basic volume, but no input selection and such. I know the remote is still good because I can program in my TV code and CD code and it controls them without a hitch. But the normal tuner control functions don't work at all. Almost like the tuner programming code was lost.

Its an RC-R0608 remote. Does anyone have any idea what this might be? I tried the factory reset described in the manual, but that just erases the codes for the other devices.

I don't know what is wrong with the original remote. Possible the setup code for the receiver portion has been corrupted, but I have no idea how you would rectify that.However, we do know that the VR309 (and other Kenwood receivers) use the NEC1 IR protocol device 184.0 for most functions, but uses 184.1 for the tuner functions. And of course the function numbers are also known.

For remotes made by Universal Electronics, it is possible to augment the built in setup codes with additional functions, and that may be a reasonable approach here. Presumably a Logitech Harmony would have Kenwood receivers in their database also. Controlling receivers with a universal remote is usually a little bit problematic because most universals have button labels and function assignments that are more geared to TVs and DVD players.

But you can program a UEI remote to control any function for the receiver.Nearly any OneForAll, many Radio Shack, Comcast cable, Cox cable, Atlas remotes provided by other cable companies, and some high end Vizio remotes can use setup code Audio 1313, 1569, or 1570. Functions which aren't implemented can be added by entering a 5 digit EFC. If you don't have any of these remotes laying around, the RCA RCRP05B ($20 at Walgreens or Best Buy) is a good choice.

I also have a Kenwood RC-R7050 remote control with the sticky surface condition. It appears to be migration of the plasticizer from the plastic body, the same condition as my sticky car dashboard. After much trial and error I have found one way to deal with it. First I take the remote apart and work only on the plastic body. The circuit board and insides were not affected. I used a silicone vinyl and rubber polish on the tacky surface to mix with the plasticizer without harming the surface of the plastic. Then I scrubbed the mixture off the surface using Dawn liquid dish detergent. The surface looks and feels as good as new although it may get tacky again in the future as more migration occurs. Thanks for all the great info on IR receiver repair.

I am floored. After being frustrated for almost two years with a Kenwood VR-507 and a RC-R0720 remote, I came across this thread. So I had to try it. Tapping is the answer. I cant believe it works! Im going to submit this thread to Kenwood. I emailed them about the problem about a year ago or more and they told me to reset the reciever and change the batteries in the remote. I wanted to punch the guy that responed to that. Anyway, maybe they'll look into it? Ill also cc the better business bureau to the link. If nothing else, maybe it will get someone to look at it.

Plazman30 ,...You deserves a Medal !Thank you for solving this problem and everyone else who contributed ....Its one of these problems that keep you lying awake at night.....Works for a while, then it doesent work, pulling the remote apart...buying new remotes.......so simple its fantastic.....Thankyou again
